Boiler losing pressure | Screwfix Community Forum

2021/5/9 · The first easy check is - repressurise the system to, say, 1.5 bar, cut the power to the boiler so it cannot come on, and then shut off both isolating valves under the boiler with 22mm pipes - make sure it's the CH 'flow' and CH 'return'. Leave it for as long as you'd notice the pressure drop.

Abstract. The purpose of a boiler draft system is to provide the air needed for the combustion of fuel and to discharge the flue gas produced in the furnace. In early days, gas passages in boilers were large. As a result the pressure drop owing to the flow of fluids through these passages was small. So most boilers did not need any external
